Yes, i'd realize about this. It's the key problem, so all features that require you to press key will not works. Do you know since when it happened ? I've tried older script(before drone update) and faced the same problem. The server's side built-in function that's supposed to be called when player press a key is not even called. But, it works fine in client-side script..
I've found a weird fix, let me know if it's still not working..
